油酸钠体系下铁离子活化石英的吸附特性
Adsorption Characteristics of Iron Ion Activated Quartz in Sodium Oleate System
摘要
Abstract
This is an essay in the field of mineral processing engineering.The effect of Fe2+ and Fe3+ on the flotation behavior of quartz in the oleic acid anionic collector system was studied by pure mineral flotation test,and the mechanism of Fe3+ activated quartz was studied by infrared spectroscopy,atomic force microscopy imaging analysis and Zeta potential measurement analysis.The results of pure mineral flotation test showed that the activation effect of Fe3+ was stronger than that of Fe2+,and the capture effect of sodium oleate was stronger than that of sodium linoleate under the condition of Fe3+ as the activation ion.The results of infrared spectroscopy and atomic force microscopy showed that sodium oleate could not effectively adsorb on the surface of unactivated quartz minerals,but could effectively adsorb on the surface of quartz activated by Fe3+.The results of Zeta potential analysis showed that the positive potential of quartz surface activated by Fe3+ reached the maximum at pH 6.0,and the activated quartz was basically positive.关键词
